Risk adjustment
Q02 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 182 Spinal Cord Disorders/Injuries0.478 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score. Look up the whole chart to see which of its HCCs the hierarchy would zero.
